Title: Developing device
Inventor: SUGA YOSHIHARU
IPC: G03G15/08
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To prevent the replenished fresh developer from being discharged, and to satisfactorily replacing the deteriorated developer with fresh developer by providing such as first and second transporting members capable of transporting in severally reverse direction while agitating the two component developer, severally arranged in the first and the second developer agitating area. SOLUTION: In this developing device, the first transporting member R1 arranged in the first developer agitating area 43 and the second developer transporting member R2 arranged in the second developer agitating area 44, severally transports the two component developer in the reverse direction while agitates therefor. Then, in the case of consuming the two component developer, the fresh developer is replenished from the developer replenish port 48 in the developer container 41. Moreover, the excess developer is discharged from the developer discharging port 52 formed on the developer flowing direction upstream side adjacent to the developer replenish port 48. Accordingly, fresh developer is replenished in a position adjacent to the developer discharging port 52 on the downstream side, therefore prevented from being discharged in stead of the excess developer, and thus the residual developer is satisfactorily replaced by the fresh developer.

Title: Balanced modulator
Inventor: BUN TADATAMI
IPC: H03C1/54
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a balanced modulator whose adjustment is easy and which obtains a large output signal. SOLUTION: A carrier C is inputted to a distributing part 11 and carriers C1 and C2 which have phase different by 90 deg. are generated and applied to a HEMT (hetero-field effect transistor) 21 of a domain ground and a HEMT 31 of a source ground 31, respectively. When a modulation signal is 'L', the HEMTs 21 and 31 are in off states and operate as capacitors and amplitude modulation signals M1 and M2 which have the same amplitude and have phases different by 90 deg. are outputted to their output sides. The signal M1 is performed fine adjustment by a phase shifter 40 and given to a synthesizing part 50. The part 50 delays the phase of the signal M2 by 90 deg. and adds it to an amplitude modulation signal M1A and a balanced modulation signal O becomes zero.  When the signal M is 'H', the phase of an output side of the HEMT 31 is inverted, because the signals M1A and M2 are added in the same phase by the part 50, the signal O that has a large amplitude is acquired.
